U.S. Pat. No. 8,176,599, titled “CINCHING AND BUNDLING TIE” filed Mar.1, 2010, describes a cinching and bundling tie. U.S. Pat. No. 8,176,599is herein incorporated by reference in its entirety.

FIG. 1A illustrates a face shield system 100 with adjustable tensioningstraps in accordance with the embodiments disclosed herein. The faceshield system 100 can generally comprise a face shield sheet 105. Theface shield sheet 105 can comprise a generally transparent material. Thetop edge 110 of the shield sheet 105 can have a substantially straighttop edge. The lower perimeter of the face shield sheet 115 can becurved, concave, or U-shaped. The face shield sheet 105 can be selectedto be sufficiently wide and flexible to partially wrap around a humanhead. The face shield sheet 105 should be selected to be a material thatis flexible, such as plastic. It is preferable for the face shield sheet105 to be relatively thin to reduce cost and weight of the system 100.In certain embodiments, the thickness of the face shield sheet 105 canbe selected to meet safety standards for a given application.

A reinforcement tab 120 can be installed along a top portion 110 of theface shield sheet 105. In certain embodiments, multiple reinforcementtabs 120 can be overlaid or distributed on the face shield sheet 105 toimprove the structural integrity of the system 100. The reinforcementtab 120, can be (but need not be) transparent. The reinforcement tab 120can be configured of a stiff rubber or plastic material. In certainembodiments, the reinforcement tab 120 can be integrated in the faceshield sheet 105, and can comprise a generally thickened section ofmaterial. In other embodiments, the reinforcement tab 120 can comprisean independent stiffened strip, such as a plastic strip, with adhesive125 on one side. In such embodiments, the reinforcement tab 120 can beadhered to the upper area of the face shield sheet 105. Thereinforcement tab 120 can be installed on the inner facing surface orthe outer facing surface of the face shield sheet 105.

The reinforcement tab 120 or band stiffens and thickens the face shieldsheet 105 at the forehead mounting point, which has multiple benefits.The reinforcement tab 120 keeps the entire face shield sheet 105 morestable on the forehead, decreasing deflection of the shield system 100.The reinforcement tab 120 can also stiffen the mounting holes 130 toallow for reusability of the shield and to avoid tearing of the faceshield sheet 1-5. The reinforcement tab 120 allows for the use ofthinner films for the face shield sheet while maintaining the faceshield integrity.

The reinforcement tab 120 can generally be formed of a stiff but pliablematerial (such a plastic) and can extend from one of the lateral sides135 of the face shield sheet 105 to the other. In certain embodiments,the reinforcement tab 120 can be biased with a curvature so as to beconcave and match the contour of a human head.

Mounting holes 130 can be formed in the face shield sheet 105 and/or thereinforcement tab 120. The mounting holes 130 can include hole chads140, that can be removed to reveal the mounting holes 130. The holechads 140 can be “punched” into the face shield and/or reinforcementtab.

As illustrated in FIG. 1B, the face shield system 100 can furtherinclude a head mount 150. The head mount 150 can comprise a cube orcuboid, formed of a generally soft or malleable material such as foam orrubber. The head mount 150 can generally match the 2 dimensional profileof the reinforcement tab 120 but can be configured to be slightlyshorter than the distance between the respective strap mounting holes130, so that the head mount 150 does not cover the strap mounting holes130. One surface of the head mount 150 can be coated with an adhesive155. The adhesive 155 can be covered again, by a cover 180 (e.g. aremovable paper cover). The head mount 150 can be installed on the innersurface of the face shield sheet 105, for example, along the twodimensional outline of the reinforcement tab 120, by removing the papercover 180 over the adhesive 155 and adhering the head mount 150 inplace. The outward extending shape of the head mount 150 allows the faceshield system 100 to be comfortably worn in front of a human's face andcan generally be fitted along the forehead region of the wearer. Theshape also holds the top edge of the face shield sheet 105 away from theuser.

The adhesive 155 on the head mount 150 can be configured so that thehead mount 150 can be removed and reinstalled on the face shield sheet105. The removal of the head mount 150 allows the components of thesystem 100 to be cleaned and sterilized individually before beingreassembled for use.

The face shield system 100 further comprises a cinch strap 160, asillustrated in FIG. 1C and FIG. 1D. The cinch strap 160 can comprise ahead band used to hold the face shield system 100 in place. To that end,the cinch strap 160 can be configured to fit around a user's head, andinterface with the face shield sheet 105 at its two edges. In certainembodiments, multiple cinch straps 160 can be used to engage withmultiple sets of mounting holes 130 on the face shield sheet 105 to holdthe face shield sheet 105 in place.

The cinch strap 160 is illustrated in FIG. 2. The cinch strap 160 cancomprise a planar, flat strap 205 having a length (l) and generallyuniform width (w) made from any pliable semi-rigid material, such aspolyethylene or polypropylene. The strap 205 also includes a first edge210 and a second edge 215. The thickness of the strap 205 will varydepending on the material used for manufacture, though a thickness ofless than some fraction of the width of the strap. Along most or theentire length of the two opposing edges 210 and 215 of the strap 205 areteeth 220 in a repeating and uniform pattern having a width (w′) and alength (l′). The teeth 220 are generally formed during creation of thestrap 205 and therefore, are continuous with the strap 205. In oneembodiment, the teeth 220 are separated troughs 225 being inverse inshape to the teeth 220. An alternate embodiment the cinch strap issmooth and lacks teeth at the distal ends 170 of the strap 205 in orderto allow a more ergonomic and comfortable handle.

The teeth 220 in the cinch strap 160 are specifically designed to engagein the mounting holes 130. In particular, the teeth 220 on either sideof the strap 205 are configured to pass through the mounting hole 130but not easily pull back out. The mounting holes 130 can thus begenerally circular in design with a widest diameter that is wider thanthe body 230 of the cinch strap 205 but narrower than the width of thecinch strap 160 measured between opposing teeth 220. As such, the cinchstrap 160 can be locked into place by grabbing the face shield sheet 105at hold points 165 at the top of the face shield sheet 105, insertingthe cinch strap 160 through the mounting hole 130, and then pulling thecinch strap 160 through the hole. In certain embodiments, the strap 205can be used to pull the face shield 100 tight into place on a user'shead.

The cinch strap 160 geometry is such that it can be threaded into themounting holes 130 on the face shield sheet 105. The cinch strap 160allows the system 100 to be fully adjustable with tightening by pullingon the cinch strap 160 while holding the shield edge hold points 165 andpulling on cinch strap 160. The cinch strap is loosened by slightlybending the edge of the shield to disengage the teeth on the cinch strapfrom the mounting hole edges.

FIG. 3 also shows an enlargement of a single tooth 220 and an angle oftaper from the top of the tooth 220 to the strap 205 of 75 degrees whichresults in the most secure locking of teeth 14 when the tie 10 isengaged. The degree of taper can range from 70 degrees to 85 degrees. Ithas been determined that the tightest and most secure lock can beachieved if the width (w′) of a tooth 220, at its widest point, is onefourth the width (w) of the strap 205, It has further been found that atooth length (l′) of one half the width (w) of the strap body 230achieves the most secure cinch. These attributes create a cinch strap160 that allows the strap to hold firmly through the mounting hole 1130in one configuration and easily release from the mounting hole 130 asnecessary when the length of the cinch strap 160 needs to be adjusted sothe face shield system 100 can be removed.

FIG. 4 illustrates a method 400 for securing a face shield system 100 inaccordance with the disclosed embodiments. The method 400 begins at 405.The first step 410 is to install a reinforcement tab along the top edgeof the face shield. The reinforcement tab is critically important as theface shield sheet may be insufficiently stiff without the reinforcementtab. In certain, embodiments, the reinforcement tab may be pre-installedon the face shield sheet.

Next, at step 415 the protective film on the head mount can be removedto expose the underlying adhesive on the outer surface of the headmount. The head mount can then be installed on the face shield, at step420 by joining the head mount to an upper portion of the face shieldsheet (approximately aligned with the reinforcement tab). This isaccomplished by pressing the adhesive covered side of the head mountonto the face shield sheet.

Next, at step 425, the hole chads can be removed to expose the mountingholes on the edges of the face shield sheet and/or reinforcement tab. Incertain embodiments, this can be accomplished by using a poking device,like a pencil or other such device to poke the hole chads out.

With the hole chads open, the ends of the cinching straps can beinserted into the mounting holes on the two sides of the face shield asshown at step 430 and step 435. In certain embodiments, the cinch strapsends can be inserted such that the perimeter of the strap and faceshield is larger than the circumference of the user's head. This allowsthe assembly to be brought into position, as shown at step 440, with thehead mount roughly resting on the user's forehead. At this point, thecinch strap ends can be pulled further through the mounting holes tocreate a snug fit around the user's head as shown at step 445, and themethod ends at 450.

In other embodiments, a face shield system 100 can be configured tointerface with a helmet as illustrated in FIG. 5. It should beappreciated that many of the aspects of the embodiment illustrated inFIG. 5 are also illustrated in FIGS. 1-3. In certain embodiments, thecinch straps 160 can be inserted from the outward facing side of theface shield sheet 105, inward. The cinch strap 160 can be secured to ahelmet 505. The cinch strap 160 can then be tightened to hold the faceshield sheet 105 in place below the helmet 505 as illustrated in FIG. 5.

In still other embodiments the face shield system can include the use oftwo cinch straps 160. The first cinch strap 160 can be inserted throughone of the mounting holes 130 and the other cinch strap 160 can beinserted through the other mounting hole 130. The cinch straps 160 canthen be tied together forming a loop with an overhand knot, or othersuch knot. The cinch strap ends can be pulled to tighten the assembly inplace on a user. This embodiment is useful in situations where the useris wearing a head cover, as in FIG. 5, and a single strap isinsufficient to fit around the head covering. The use of two cinchstraps is therefore particularly useful for users who may need a facecovering while wearing a helmet 505 or other such head covering.
